A B-1B Lancer touches down at Ellsworth Air Force Base, S.D., after completing a nearly 29-hour round-trip sortie to the Pacific theater of operations April 22, 2020. The sortie demonstrated the U.S. Air Force’s dynamic force employment model and tested the airframe’s ability to integrate with multiple Air Operations Centers in multiple areas of responsibility.
